Hospital
From Equestripedia, the Archives of Equestria!
A hospital is a health care and wellness insitution that provides patients with specialized medical and nursing staff and medical equipment. Hospitals appear throughout developed countries such as Equestria, Ponyland and the Crystal Empire and in Equestrian history dates back to at least the Era of Two Sisters.
Hospitals exist for animals as well, but are often referred to as vets or clinics.
